Earlier this month, Paradox and Iceflaker Studios revealed that the next update for its hit city simulator, Cities: Skylines 2, would add a benchmark tool and numerous gameplay fixes to address performance issues. Today, it was revealed that the patch, titled Spring Cleaning, would be coming out at the end of April 2026.
Cities: Skylines 2 City Corner #5 is all about spring cleaning, as this update focuses on long-requested quality-of-life features, UI adjustments, and significant bug fixes.
Historical Buildings now have a new toggle that prevents specific buildings from leveling up or changing their physical appearance, allowing you to preserve the look of a level 2 building even if it reaches max level. The addition of a dedicated UI button will now consolidate all active mods in one place, preventing icon clutter and overlap in the game interface.
The long-awaited benchmark tool is finally here, letting players check performance between patches and how updates affect performance on each individual computer, while also giving developers a chance to gather data on which areas and types of hardware need more focus. On the user interface side, an option has been added to adjust the toolbar’s size and transparency (0–100%); scaling the toolbar also scales buttons and other elements for better accessibility.
To help with traffic management, Iceflaker Studios has removed citizens’ ability to move in and out of the city by taxi, which was identified as a major cause of traffic jams. An issue with public transit has also been resolved, as the “permanent boarding state” bug, where buses, trams, and subways would get stuck at stations and never depart, is no longer present.
Other bug fixes include a critical issue in the Bridges & Ports DLC where commercial/industrial buildings ignored ports for importing goods and storing mail, and the issue of excessive student numbers in elementary schools that forced players to overbuild schools. The “Urban Cycling Initiative” policy will now also increase the likelihood of bicycle use from 20% to 50%, making bike-centric cities more viable.
The developers have already started planning and preparing the next patch, which includes more bug fixes and adjustments to traffic and pathfinding.
